is only an example how commercial solutions work. not to be done at home.

ok aviko, i am aware of this fact.

but i guess only few of us with this problem understand native polish language.....

therefore we follow(ed) Gradius2's version/solution.

but now is seems that there are main differences, for example, u say to skip the 'i4,1,22' command, also the POWER OFF, waiting 10secs and then POWER ON of the drive, which Gradiu2 says wouls be 'very important'......

since most of us are newbies, who are not familiar with all these commands and their function, we are somewhat confused.....

thanks

cmburns

because Gradius2 lost in translation information about it was only example how other tools work.

My ST3500320AS doesn't spin on anymore. This evening I wanted to try this workaround (busy mode) again. But after connecting the hd to the powersupply nothing happened.

In bios: 0MB, under OS X in the disk utility: 2 TB. ?!

It seems that you burned motor ic, Im almost sure that you connect motor when pcb was not stopped and gives voltage to motor. Thats why I told its was really stupid to disconnect it, you will not know when motor is powered and when not.

Does drive making any sounds? (it can be really silent, just put ear on it and power on). Does drive says anything on terminal? Maybe something like this: Buzz Buzz Buzz if yes, it means that microprogram is trying to start motor but could not. Let me know.

is this complete? is this i need to try? is there any error, did i forget anything?

I should be done. You can try spin down and spinup drive (from level 2>Z and then U) after it spins go back to T ( with /) then type F3 T>F712 (as I remember its was 712 in 500g) it should be 4 parameters last one CONGEN READ FROM MEDIA, 1 means drive reads properly parameters from platters and its really good. If its 0 send command F3 T>/2 and then F3 2>x1 and paste results here

if you not see CONGEN in F712 type F list will be long and CONGEN should be at position 716

@edit:

I dont have any drive from this family here at this moment to check on myself these commands, so everything I told was from my head. Sometimes I could be wrong.

I did a mistake in last command but Yura noticed me that. Now its fixed.

I see many people reading this thread now. I have to say everyone case is a little different and have to be studied separatelly. I really dont have time to help all of you. If you decide to repeat steps that I wrote to all above, please dont be mad if it will not work for you.

Thats why I really think it will be hard to develop universal solution which will work in ANY case.

aviko, from your experience is it safe to swap pcbs and run the firmware for those of us who are not good with electronics/coding?

If you mean 7200.11/ES.2/Diamondmax22 series it will not work. Connect only pcb without hda to pc and recognize it in bios or any other software. there will be capacity 0mb but serial number should be visible. What is that mean? It means that individual for any single hdd data are stored on its own pcb. Unless you do some work (sorry i cant tell you in simple words how exactly you need to do) it will not work. Use your brain/google/help someone and consider do you really have experience and proper tools to do that.

@edit:

as I underestand you mean swap pcb from another hdd right? Or by swapping you mean removing its own and put back together due all above steps in solution.
